COTH(number)

Returns the hyperbolic cotangent of a number.

numberThe angle.

Remarks

* Added in Excel 2013.
* The hyperbolic cotangent of a number is 1/TANH.
* The hyperbolic arctangent of a number is the inverse of the TANH.
* If Abs(number) > 2^27, then #NUM is returned.
* If "number" is not numeric, then #VALUE is returned.
* You can use the TANH function to return the hyperbolic tangent.
* You can use the SECH function to return the hyperbolic secant.
* You can use the CSCH function to return the hyperbolic cosecant.
* You can use the ACOTH function to return the hyperbolic arc-cotangent.
* For a working example refer to the Quant > Hyperbolic Functions page.
* For the Microsoft documentation refer to support.office.com
